On what does Andrew base his demand for this change? Andrew since you have a degree in marketing can you cite the studies indicating the market for this new non-F16 class so many builders are waiting to jump into?

With the number of very skilled tinkerers and hobbiests on the planet, surely one of them would have built your lightening fast, stiff beyond belief, all unobtanium rocket just as a proof of concept.

I think it far more likely that the F16 market is well met by the builders and models currently available.

I know! Your extra heavy non-F16 would be the perfect replacement for all those f17s currently being sold.
